The invention discloses an
image fusion enhancement method for a multi-
signal-source
liquid crystal splicing screen, and relates to the technical field of large-screen display control, and the method comprises the steps: building a virtual coordinate
system taking a physical gap as a reference at an input end, carrying out the decoding,
time synchronization and unified mapping of a multi-source heterogeneous
signal, converting the multi-source heterogeneous
signal into a unified
color space, and carrying out the
image fusion enhancement of the multi-signal-source
liquid crystal splicing screen. The display consistency of different signal sources is ensured; then, a compensation model based on a brightness
attenuation function is introduced into the splicing boundary area, edge
pixel brightness is subjected to self-adaptive correction, and brightness unevenness caused by physical gaps is relieved; calculating the content complexity based on the row-level
gradient magnitude in the fusion screen area, dynamically constructing a content-sensitive fusion weight, and carrying out weighted fusion on the images on the two sides to generate a transition
image frame; and through joint output of the transition
image frame and the original side
image frame, visual seamless connection of the splicing gap area is realized. Therefore, the integral continuity and
visual experience of tiled display are effectively improved while the image detail fidelity is ensured.
